The cam adjustment solenoid blanking plate is used to block off the oil passageways when deleting variable valve timing (VVT) from 1999 and newer Volvo RN block engines. This is most commonly needed when doing "RN swaps", or when you put a 1999+ revision N engine into a car earlier than 1999 that doesn't have the software to control the camshaft actuator. The blanking plate is manufacturing using thick, 6061 Aluminum and features a hard black anodized coating and laser etched snabb logo. Please note: Gasket is not included.
